Ashwagandha, a potent herb revered in traditional Ayurvedic medicine, has been gaining recognition in the modern world for its myriad health benefits. One area that has sparked considerable interest is its potential impact on testosterone levels.
This article examines Ashwagandha's potential to boost testosterone, reviewing relevant studies and anecdotal experiences, and discussing benefits and precautions.
Testosterone is a vital androgen hormone, often associated with masculinity, though it plays crucial roles in both men and women's bodies. In men, it's primarily produced in the testicles and is responsible for the development of male reproductive tissues, including the testes and prostate.
Testosterone influences secondary masculine characteristics like facial hair, and overall health, including muscle growth, virility, libido & fertility.
Low T levels can result in reduced bone density, muscle mass and energy, particularly in men. Age, diet, lifestyle, and certain medical conditions like Type 2 Diabetes, metabolic disorders and hypogonadism may lower testosterone levels.
Understanding these factors is key when considering interventions like Ashwagandha to boost testosterone.
Ashwagandha and Its Potential Effects on Testosterone
Ashwagandha, also known as Withania somnifera, an evergreen shrub that grows in parts of the Middle East, Africa, and India has been used for centuries in Ayurvedic medicine for its wide-ranging health benefits. 
Ashwagandha is believed to have a wide range of applications, including enhancing digestion, lowering body fat, lowering inflammation, and boosting muscle mass. There are even indications that the herb and its derivatives might possess properties that combat cancer. [2, 3]
One of the most intriguing potential benefits is its ability to influence testosterone levels.
But how exactly does Ashwagandha exert this effect?
1). Adaptogenic properties & Stress Reduction
One of the primary ways Ashwagandha might influence testosterone levels is through its adaptogenic properties. Adaptogens are substances that help the body adapt to stress, and Ashwagandha is one of the most well-known.
Stress triggers the release of cortisol, initiating the fight-or-flight response, vital for survival. However, chronic stress creates a continuous surge of cortisol, maintaining a constant fight-or-flight state, harmful to the brain and body.
Chronic stress may lead to lasting inflammation, a compromised immune system, and various potential problems including hormonal imbalances like decreased testosterone levels. (Source) .
By helping the body manage stress, Ashwagandha could potentially help maintain or even boost testosterone levels.
A study published in the Indian Journal of Psychological Medicine found that Ashwagandha effectively reduced stress and anxiety, which could indirectly support testosterone production. 
2). Increasing LH levels
Another mechanism through which Ashwagandha increases testosterone levels is by increasing the production of luteinizing hormone (LH). LH is a hormone produced by the pituitary gland that plays a crucial role in testosterone production by the testes.
A study published in the American Journal of Men's Health found that Ashwagandha supplementation increased LH (luteinizing hormone) levels and DHEA-S levels, which could potentially lead to increased testosterone production. 
3). Reducing cortisol levels
Ashwagandha might also enhance testosterone levels by reducing levels of cortisol , a hormone that's released in response to stress. High cortisol levels can inhibit testosterone production. By reducing cortisol levels, Ashwagandha could potentially support testosterone production.
The study published in the Indian Journal of Psychological Medicine found that Ashwagandha effectively reduced cortisol levels in adults with chronic stress. 
4). Reducing oxidative damage
Ashwagandha is recognized for its potent antioxidant attributes, which may shield the testicular cells from oxidative harm. Since the testes are the primary site of testosterone production, minimizing damage to them could sustain testosterone levels, and in turn, support the reproductive system. 
High levels of stress, especially oxidative stress, can negatively impact both libido and sperm quality, and may also disrupt testosterone levels and functions. Ashwagandha, as a natural enhancer of testosterone, could potentially alleviate oxidative stress within the body, simultaneously bettering some of the signs associated with low testosterone.
5). Direct stimulation of enzyme activities in the testes
It's also worth noting that Ashwagandha might have a direct effect on the testes, the primary site of testosterone production in men. Animal studies, like the one published in Evidence-Based Complementary and Alternative Medicine, have shown that Ashwagandha can stimulate enzyme activities in the testes, which could potentially boost testosterone production while aiding in stress-related male infertility.

Review of Studies on Ashwagandha and Testosterone
The potential of Ashwagandha to boost testosterone levels has been the subject of numerous scientific studies. Let’s delve further into some of these key studies and discuss their results and implications.
One of the most notable studies was published in the Journal of the International Society of Sports Nutrition. The study involved 57 male participants aged between 18-50 years, who were given either 300mg of Ashwagandha root extract twice daily or a placebo for eight weeks. 
The results showed that the group taking Ashwagandha had significantly higher increases in testosterone levels compared to the placebo group. The participants who received ashwagandha root extract supplements twice daily experienced notable enhancements in muscle strength, size, and recovery.
This study suggests that Ashwagandha might enhance testosterone levels and improve physical performance & muscle mass in healthy men, showing its potential benefits in muscle growth, working out, lifting weights & bodybuilding.
Another study published in the Journal of Evidence-Based Complementary & Alternative Medicine involved 75 men undergoing infertility screening. The men were given 5g of Ashwagandha root powder daily for three months.
The results showed a significant increase in testosterone levels in the Ashwagandha group. This study suggests that Ashwagandha might improve testosterone levels and aid men with fertility issues. 
A study published in the American Journal of Men's Health involved 57 men with chronic stress showed how to use it for boosting Testosterone. The participants were given either 240mg of Ashwagandha extract daily or a placebo for 8 weeks. The results showed that the Ashwagandha group had a significant reduction in stress and a significant increase in testosterone levels compared to the placebo group.
The research revealed an average testosterone increase of approximately 15 percent, along with an 18 percent rise in DHEA-S levels, a hormone instrumental in the production of other hormones, including testosterone.
This study suggests that Ashwagandha might boost testosterone levels by managing stress, and also directly by increasing LH levels.
At least 2 studies support the notion that Ashwagandha has a direct effect on increasing Testosterone levels- by increasing LH (Luteinizing hormone) levels according to American Journal of Men's Health, and by stimulation of enzyme activities in the testes, according to Evidence-Based Complementary and Alternative Medicine.
Another study conducted in 2022 revealed that ashwagandha increased serum testosterone levels by 17 percent in men experiencing a low sex drive. 
Other Ashwagandha Studies related to Testosterone
Several studies indicate that ashwagandha root could aid in addressing certain types of male infertility. .
Another comparable study revealed that supplementation with ashwagandha root powder helped men dealing with infertility issues related to stress .
Fertility is a multifaceted matter with no singular solution, but scientists are exploring whether ashwagandha can enhance vitality & quality.
A review encompassing four studies focused on men who took ashwagandha revealed that supplementing with the herb for a period of 60 to 90 days led to improvements in vitality, seed count, and hormone levels, as determined by research published in Evid Based Complement Alternat Med. 
Nonetheless, it's vital to recognize that enhancing fertility does not equate to an increase in testosterone levels.
Considering the indications that ashwagandha may boost testosterone levels and fertility, it's logical to inquire whether the herb might also address a prevalent issue: ED.
Unfortunately, research on ED and ashwagandha is sparse. A 2011 trial pitted ashwagandha against placebo powders in treating ED stemming from psychological factors like stress and anxiety, but the herb did not work for this purpose. 
Potential Benefits of Increasing Testosterone with Ashwagandha
Increasing testosterone levels can have a multitude of potential benefits, and Ashwagandha, with its adaptogenic properties, might play a significant role in this process. Let's delve into the potential benefits of higher testosterone levels and how Ashwagandha might contribute to these benefits.
Firstly, higher testosterone levels can enhance physical performance. Testosterone plays a crucial role in muscle growth and strength, making it particularly beneficial for athletes and fitness enthusiasts. Ashwagandha, with its potential testosterone-boosting properties, might support this aspect of physical health.
This study published in the Journal of the International Society of Sports Nutrition found that Ashwagandha supplementation improved muscle strength and recovery in men. 
On the mental health front, testosterone can influence mood and energy levels. By potentially boosting testosterone, Ashwagandha might help enhance mood, reduce fatigue, and improve cognitive function. One study published in the Andrology found that testosterone therapy improved mood and energy levels in men with low testosterone. 
Finally, higher testosterone levels can support healthier sex drive. Testosterone plays a crucial role in libido in both men and women, and by potentially boosting testosterone, Ashwagandha might help support a healthy sex drive.
